Well homes are more likely to be empty when people are in school or work than when they are sleeping, so break-ins to private properties might be more common at day time. Then all the white collar crime, tax frauds, bribes and such sound like day time activities. Picking pockets or scamming tourists is not really possible when there are no tourists, and your price is better if someone else did not get them already, so also mostly day time, unless operating in bars and clubs. Domestic violence, likely mostly after work evening time. Sure there are things like smuggling over land borders that might be easier at dark, but there are also lots of types that would be lot more likely at day time. Can't know without actual numbers though.

Most crime happens when the opportunity is available. So warmer weather meaning the criminal is out and about, ease of target, availability of things to justify going out at X time, etc. There's going to be a lot more night time crime in an area full of bars and clubs vs a subdivision surrounded by subdivisions.

Best time to rob houses in Skyrim is the middle of the day.
